----------------------------------
Status: Open (was: Patch Available)
> MR AM handles an oversized split metainfo file poorly
> -----------------------------------------------------

> Key: MAPREDUCE-4937
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4937
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mr-am
> Affects Versions: 0.23.5, 2.0.2-alpha
> Reporter: Jason Lowe
> Assignee: Eric Payne

>
> When an job runs with a split metainfo file that's larger than it has been
> configured to handle then it just crashes. This leaves the user with a
> less-than-ideal debug session since there are no useful diagnostic messages
> sent to the client for this failure. In addition it crashes before
> registering/unregistering with the RM and crashes without generating history,
> so the proxy URL is not very useful and there's no archived configuration to
> check to see what setting the AM was using when it encountered the error.
> The AM should handle this error case more gracefully and treat the failure as
> it does any other failed job, with a proper unregistration from the RM and
> with history.
